GRAIN-CAR DOOR.

' SPECIFICATION forming part of Letters Patent No. 463,637, datedNovember 24, 1891.

Application filed March 9, 1891. Serial No. 384,233. (No model.)

T 60% whom it may concern.-

rora, in the county of Kane and State of Illinois,,have invented certainnew and useful Improvements in Grain-Oar Doors; and I do hereby declarethat the following is a full, clear, and exact description of theinvention, which will enable others skilled in the art to which itappertains to make and use the same, reference 7 being had to theaccompanying drawings, and to letters of reference marked thereon, whichform a part of this specification.

My invention is an improvement on my patent, N 0. 272,455, grantedFebruary 20, 1883. In that patent I provided for raising twodoorsections at either side of the car and supporting them in thecar-roof, one above the other.

My present invention consists in new and improved devices for efiectingthis, and also in novel means serving the purposes of holding down thedoors, of releasing them for raising, and preventing their rattling whendown.

In the drawings, Figure 1 shows in perspective a portion of a car withmy improvement therein; Fig. 2, one of the doors detached; Fig. 3, oneof the eccentric-latch devices for holding the doors in certainpositions; Fig.

4, a partial end view of one of the doors; and Fig. 5, a detailenlarged, showing the latch in a locking position.

A and B represent horizontal straight pieces or ledges, the upper one Bshorter than the other and both secured to the frame 0 just beneath itsroof, as shown. These pieces are placed parallel with each other and maybe of wood or of metal and severally secured in any proper manner. Nogrooves are or need be cut in the frame, nor any alteration of the framewhen using these pieces.

D represents metallic plates placed 011 the inside of the car-frame, asshown, near the roof and midway of the breadth of the car, havingaspecial construction and serving not only as a stop to prevent eachraised door from being pushed too far into the roof, but also serving toretain in their places such doors when raised. Each of these has twohooks or notches d at each of its opposite sides, into which the upperpintles of the doors may drop when the doors are lodged in the ceiling.

E are vertical strips, preferably of metal, secured to the car-frame andhaving between them and the frame spaces 6, answering as 5 5 grooves,and within which the pintles f of the doors G or H may freely run.

Outside the car and secured on the vertical part of its frame arespecial devices by means of which section-doors may be held down orreleased to raise them or held against rattling when not raised. Thesedevices severally consist of a plate J, having two concave or archedrecesses or spaces 3' j made therein and a hook 9' at one side, andthese plates are pivoted to be turned each on its center It. Aneccentric or disk L, eccentrically pivoted, is placed above the plate insuch position that when the plate is swung inward so as to project abovethe top edge of a door and the disk then turned to fit snugly in theouter oneof the concave spaces the door will be locked against raising.

WVhen the plate is swung outward and similarly held by the disk lodgedthen in its inner recess or space,it offers noimpediment to the freeraising or lowering of the door. It will also be observed that when thedoor is closed a proper turning of the eccentric will press the plateagainst the outside of the door and tend to prevent its rattling.

The advantages of my improvements are many. For instance, noguide-grooves,whether straight or curved, need be cut in the woodwork ofa car; no depressions or curved parts 8 5 are made in the topguide-grooves in which to rest the pintles; no cast-iron angle-plateserving both for the vertical and horizontal grooves is needed; thelodging of the top pintles of the raised doors in the notches d is 0located centrally of the car, and the avoidance of any depression ornotches at the entrance of the horizontal grooves facilitates theraising and lowering and insures a better holding when raised.

The doors may be readily raised by suitable handles m when not fasteneddown, or after releasing any fastening that may be used within the car,and each of the plates D is adapted for the pintles of any or all of theroo doors.

I claim 1. In combination with a vertically-sliding car-door having endpintles, guideways consisting of vertical strips, of horizontal pieces AB, and of center plates D,located at the inner ends of these pieces andprovided with depressions or notches to engage the pintles, allsubstantially as set forth.

2. In combination with vertically-sliding car-doors, each having endpintles, the central plates D, each made with notches at each side ofits center, as set forth, and located centrally under the roof, combinedwith lateral guid e-strips at each side thereof and vertical strips ateach side of the car, whereby the doors when raised to the roof may allbe upheld by the lodginent of the pintles in the DON D. MILES.

' tially as set forth.
